3 ACTION ON RECEIPT Check the packing case for damages. In case you suspect any refrigerator damages, notify your supplier before unpacking. Unpack the refrigerator carefully. Check the refrigerator. If it is damaged, notify your supplier. 4 Check that the flue baffle is hanging inside the chimney, see page 4. 5 Read the operating instructions in the manual or this handbook and follow them exactly. Make sure that the correct burner jet for the gas available (propane or butane) is fitted. It may be necessary to change size of burner jet. installation Place the refrigerator in the coldest possible place inside a building. The refrigerator is tested to operate reliably in temperatures up to 4 C. The room must be ventilated and free air circulation around the refrigerator is necessary. Keep the refrigerator in the shade and away from heat of any kind. 4 Avoid draughts, such as door and window openings mm 5 Clearances to wall must be at least 5 mm and to roof at least 00 mm. 5 mm 6 7 Check that the door seals properly against the cabinet, see page 8. Ask for the local gas suppliers advice as to what material to use for gas connections. 8 If electricity is used, check that the voltage is correct. If possible, let an authorized technician make the gas installation. A gas regulator must be fitted to the gas bottle.

5 CONTROLS The refrigerator can be powered by either mains electric or LP gas. Changing between these modes of operation is carried out by means of control buttons positioned as shown in the figure. The energy selector [E] can be set at either I (mains electric), D (LP-gas) or 0 (off). The refrigerator temperature is controlled by a thermostat [D]. Please note that the thermostat has no off position. The refrigerator is fitted with a safety device which automatically shuts off the supply of gas if the flame goes out. The safety device can be opened manually by depressing knob [C]. A B C D E First time the refrigerator is used, smoke will appear due to paint residues in the chimney. The piezoelectric igniter discharges sparks over the burner when the button [B] is depressed. In the flame viewer [A] you can see a blue light when the flame is alight. lp gas operation Make sure that all valves between the gas container and the refrigerator are open. Turn the energy selector [E] to position D. 4 Check the flame indicator [A] to see whether the flame is alight. 5 Keep the safety device control depressed for a further 0 5 seconds. 6 After initial installation, servicing, or changing gas cylinders etc, the gas pipes may contain some air which should be allowed to escape by briefly turning on the refrigerator or other appliances. This will ensure that the flame lights immediately. Depress the safety device control [C] and hold it down while depressing the piezoelectric igniter button [B] repeatedly. Release the safety device control and again check to see that the flame is alight. To terminate gas operation, turn knob [E] to 0. Electrical operation Set the energy selector [E] to position I. regulating the temperature It will take several hours for the refrigerator to reach normal operating temperature. The temperature of the main compartment of the refrigerator is controlled by a thermostat. The thermostat knob [D] should be set at 5. If a lower (colder) temperature is desired, set the thermostat to a higher figure.

6 DAILY OPERATIONAL ACTIONS Check the temperature inside the refrigerator. To regulate the temperature see page 5. If LP-gas is used, check that the burner flame is blue, through the sight glass. To ensure continuous operation a spare gas bottle should be available. Replace the gas bottle before it is absolutely empty. If possible, weigh an empty bottle and note the weight. WEEKLY OPERATIONAL ACTIONS Check the frost formation on the cooling element. If the ice is thicker than 6 0 mm (/4 /8 inch) defrosting should take place, see page 9. Frost forming rapidly (in just a few days) could be result of poor door sealing, see page 8.

7 MONTHLY OPERATIONAL ACTIONS Check that the condenser and cooling unit are free from dust. Check the outer cabinet for paint damage. Repaint if necessary. When necessary: Clean the refrigerator in and outside with a damp cloth. Use mild detergent only Clean door gasket. ANNUAL OPERATIONAL ACTIONS Clean the burner jet, see page. Check the gas line connections for leaks, see page 8.

8 CHECKING THE DOOR SEAL Place a thin paper strip against the cabinet front. Close the door. Check all the way around the door. Pay particular attention to the corners. Pull the paper strip, if it moves easily or falls away by itself: Find the place where the rubber gasket doesn t seal tightly, then Place a pad of paper or sticking plaster between the rubber gasket and the inside of the door. In order to make the gasket seal tightly. 4 If you can not make the door seal tightly, order a new door, see page 9. CHECKING THE gas equipment for leaks Dissolve some soap in a small quantity of water. Brush all equipment joints with soapy water. Watch the joints for bubbles. 4 Bubbles indicate a leak. A leaking joint must be attended to either by tightening or replacing the leaking part.

9 DEFROSTING It is normal that frost forms on the cooling element. A thin layer of frost does not affect the cooling performance. A thick layer of frost (6 0 mm or /4 /8 inch or more) must be removed by defrosting. Move the vaccine to another refrigerator if available or store it in a coolbox with ice packs. Turn off the refrigerator and leave the door and the freezer compartment shutter open. Remove ice with your fingers, as soon as it is possible to do so. Do not use knives or sharp instruments 4 Empty the drip tray. 5 Wipe the freezer compartment and cooling element dry. 6 Clean the refrigerator inside. Use mild detergent only. 7 Start the refrigerator on gas or electricity. Defrosting is to be carried out as quickly as possible in order not to damage the vaccine. Use the time it will take to defrost to clean the refrigerator etc. Wait until the vaccine compartment is cold before replacing the vaccine. cleaning the refrigerator It is advisable to clean the refrigerator inside when defrosting. 7 Use warm (not hot) water and mild household detergent. Never use scouring powder, steel wool or similar. 4 Do not forget to clean the door gasket. 5 Before starting the refrigerator again, wipe all parts dry. 6 Put the vaccine back as quickly as possible. 7 Clean all external parts with a soft brush or a piece of cloth. Particularly the cooling unit should be kept clean for best performance, see illustration.

10 gas OPERATION: CHECKING THE thermostat 0. Turn the thermostat control knob, to the lowest position (0). The flame should now burn with a small flame (by-pass flame). Watch the flame in the sight glass or remove the cover from the burner to watch the flame. Turn the control knob towards the highest position (MAX). If the flame changes into a bigger one the thermostat is functioning. If no change in flame size can be observed, the thermostat is faulty, see page 4 for replacement.

11 ELECTRICAL OPERATION: checking the thermostat and heater Pull out the plug from the wall socket. Remove the plastic cover on the thermostat. 4 Remove electrical cables from the thermostat. By-pass the thermostat by cennecting the cables using tape or sticking plaster. Make sure to insulate the metal ends completely. 5 Push the plug into the wall socket and put the refrigerator on test for at least 4 hours. 6 If the refrigerator gets cold the thermostat should be replaced, see page 4. 7 If the cooling unit does not get warm, replace the heater, see page 5. Do not attempt this procedure without the proper knowledge of electrical components. 4 Insulate metal ends completely. Use tape or sticking plaster. When finished, do not forget to put the wires back on the thermostat.

12 CHECKING THE thermo-element Check that the joint [A] between thermo-element and flame failure device is tightened properly. Check that the tip [B] of the thermo-element is located in the flame. Check the flame failure device (below). A B CHECKING THE flame failure device Press the flame failure device button to its stop. Light the burner and wait for 5 0 seconds. If the flame is blown out, the flame failure device must shut off the gas supply within minutes. Test as follows: Release the button and check that the flame stays lit. If it does not, check the thermo element (above). If you already have checked the thermo-element (above), replace the thermo-element. If it is still not working, also replace the flame failure device. Blow out the flame, wait minutes. Try to light the burner without pressing the flame failure device button. If functioning correctly, it will be impossible to light the flame without pressing the button.

13 CLEANING THE burner and burner jet The main steps when cleaning the burner and the burner jet are: Shut the gas valve. Remove possible cover plates for access to burner and burner jet. 4 5 Unscrew the burner jet which is located on the gas inlet side of the burner. Clean the burner jet carefully with alcohol or petrol and blow it dry. Clean the burner with a brush and blow it free from dust. 6 Assemble the parts again. Burner jet Do not use any tools for cleaning burner jets. Do not use other burner jet sizes than the one recommended for the refrigerator model.

14 replacing thermostat 4 The main replacement procedure is the following: Shut the gas valve at the gas bottle and/or pull out the plug from the wall socket.
